B737 europe airpost and problem

Hello everyone,

We have a B737 cockpit.(ifly cbe p3dv4)
https://737projectcom.wordpress.com/

It simulates a Europe Airpost B737.

I'm currently working on a repaint of this aircraft using GIMP software.
But this is my first repaint.

I'm having trouble with the white stripes that run under the aircraft near the main landing gear.
Could you please advise me on how to position these white stripes?


Thank you.

My work

and the cockpit.
